[0002] With the rapid development of construction projects and the increasing requirements for the performance of concrete, the demand for concrete additives is also continuously increasing. Concrete additives can enhance the workability of concrete, reduce problems such as cracks and shrinkage, and improve the strength and durability of concrete. Therefore, it is necessary to design a ball mill for producing concrete additives;

[0003] For this reason, the patent with the publication number CN102114435A discloses a ball mill, which includes a barrel-shaped ball mill body. An inlet is provided at the upper part of the ball mill body, and an outlet is provided at the lower part of the ball mill body. A coupling for connecting a driving device is respectively arranged at both ends of the ball mill body. The driving device is installed on a frame for fixing the ball mill body. A pressure control device and a pressure detection device are also arranged on the ball mill body. One end of the pressure control device extends into the ball mill body to control the pressure inside the ball mill, and the other end is connected to the pressure detection device. When the ball mill is in use, through the pressure control device and the pressure detection device, the material can be mixed and ball milled while being evacuated, improving the working efficiency;

The bottom ends of the support seats 4 are fixedly connected to the top end of the workbench 1. Inside the ball mill body 6, there is an inner cavity 8. Inside the inner cavity 8, grinding balls 11 are provided. Outside the inner cavity 8 inside the ball mill body 6, a noise reduction structure 7 is provided. The noise reduction structure 7 includes a cavity 701, a shock pad 702, a first sound insulation layer 703, and a second sound insulation layer 704. The cavity 701 is opened outside the inner cavity 8 inside the ball mill body 6. Inside the cavity 701, a shock pad 702 is provided. Outside the shock pad 702, a first sound insulation layer 703 is provided. Outside the first sound insulation layer 703, a second sound insulation layer 704 is provided. The first sound insulation layer 703 is actually a sound absorption board layer, and the second sound insulation layer 704 is actually a sound insulation cotton layer. On one side of the top end of the workbench 1, a bracket 2 is fixed. At the top end of the bracket 2, a feed pipe 3 is installed. One end of the feed pipe 3 close to the ball mill body 6 extends into the inner cavity 8 through a reserved groove 14. At one end of the inner cavity 8 inside the ball mill body 6 close to the feed pipe 3, a reserved groove 14 is opened. On the side of the top end of the workbench 1 far from the bracket 2, a support plate 9 is fixed. On the outer wall of the side of the support plate 9 far from the ball mill body 6, a driving motor 10 is installed. The output end of the driving motor 10 is fixedly connected to the outer wall of one end of the ball mill body 6. The central axis of the driving motor 10 is collinear with the central axis of the ball mill body 6. At the corner positions of the bottom end of the workbench 1, support legs 13 are fixed.

[0028] The shock pad 702 can, when the ball mill body 6 is running, slow down the vibration amplitude when the grinding balls 11 collide with the protection plate 1201. The first sound insulation layer 703 is a sound absorption board, which can absorb the sound emitted by the grinding balls 11 and the protection plate 1201 and reduce the generated noise. The second sound insulation layer 704 is sound insulation cotton, which can absorb the energy of the noise, effectively control the echo and reflection, and reduce the rebound and aggregation of the noise.

[0029] Referring to the attached Figures 1 - 3 and Figure 5, a protective structure 12 is installed on the inner wall of the ball mill body 6.

[0030] The protective plates 1201 are evenly arranged on the inner wall of the ball mill body 6 and are fixed to the ball mill body 6 through the bolts 1203, so that the protective plates 1201 form a layer of protection plate on the inner wall of the ball mill body 6, avoiding damage caused by the grinding balls 11 hitting the inner wall of the ball mill body 6 when rolling inside the ball mill body 6. If the protective plate 1201 is damaged due to impact, the protective plate 1201 can be removed from the inner wall of the ball mill body 6 through the bolts 1203 for replacement. The meshing of the upper teeth 1202 and the lower teeth 1204 can increase the fixing force between the protective plates 1201.
